I loved the wii mote and wish the Wii U just upgraded on what we had there. I like the 3D in the 3DS, it's much like my phone's 3d (HTC EVO 3D), but I don't think it makes the system. I don't have a Wii U yet, so can't comment on the gamepad.

Didn't like the 3D at first, then started using it more and more, and it is a really neat little gimmick.
Didn't like the Wii mote at first, but ended up loving the motion controls (for some games).
Initially loved the gamepad... Lets hope it stays that way

I find troll topics like this thread to be useless.

I love them all...how about that ?

absolutely ! There is no going back after Metroid Blast, Resident Evil 4 and Goldeneye !

3D.
it only make diference in one game till now.

but theres a reason, not everybody can see in 3D, so a game that the 3D make all the diference (making this feature mandatory to the game progress), will be a game that is not for everyone.

the r3 and l3 button....

Easily the 3D, I barely use it anymore. The Wii mote can be a fun experience if done right. Plus if Nintendo would re design the wii mote with a upgrade, just think of the possibility free the indie industry.

Well, I never use the 3D, but I used the Wiimote quite a bit.

Stylus.. I hate the resistive touchscreen.. Wish it had a capacitive screen so the overal controls where better
